BREAD-PAN.

Specification of Letters Patent.

Patented July 28, 1914.

To'ail w'ho'm it may concern:

Be it known that I, \VILLIAM A. WHALE'N, a citizen of theZUnited States, residin at Baltimore, in the State-of Maryland, iave invented certain new and useful Improvements in Bread-Pans, of which the following is a specification.

This invention relates to an improvement in bread pans of that type where anumber of small pans form a set, each pan adapted for one individual loaf of bread, have position side by side and are secured together by bars-one bar extending crosswise of one end wall o f all the pans, and another bar crosswise of the opposite end wall of all the pans-the bars and end walls being fastened together by rivets. \Vhile this type of bread pan is very largely used an ob ection to it consists in the fact that the rivet heads are exposed at the inner surface of the walls of the pan. These rivet heads are usually steel while the walls of the pan are tin-plate; the steel rivet heads often oxidize and become rough and discolored, and in addition the exposed rivet heads are frequently slightly tilted of not flush with the surface of the pan wall. The rivet heads being exposed at the inside of the pan wall produce marks on the baked loaves of bread that are objectionable.

The object of this invention, therefore, is to provide bread-pans of the type described wherein the rivets used for the urpose named have no exposure inside of t e pan.

The invention is illustrated in the accompanying drawing in wlii'ch Figure 1 is a perspective view of a set of pans. Fig. 2 is an outside view of part 01 the end of a pan showing the rivet openings in the form of a slot.' Fig. 3 is a section of part of a pan showing the inner surface of the end. Fig. 4 isa side view of part of, a pan with the V'shaped fiapturned down. Fig. 5 is an outside view, one corner of an showing a round rivet-opening in the V- ap.

The pans are rectangular in shape and each pan has a bottom, 5, two end walls,b, and two side walls, 7 and are usually made of commercial tin-plate; each corner of the a wire extending all around.

pan is formed by producing'in the sheetmetal a V-shaped fold, 9. which lies flat against the exterior end-wall. 6; the toprim of the walls have a bead. 8, that incloses It is to be understood that. any number of these small bar, of a rivet that pans, say two, three, four or more may C0lllpose a set, the several pans included in the set being fastened together by stringer bars, 17, that extend across the exterior surface of the end walls, 6, of all the small ans. The upper edge of the stringer bar is in close contact with and below the beaded top-rim, 8, and the bar is secured to the end wall by rivets, 18, no part of which are exposed inside of the pan.

Rectangular shaped ans have heretofore had at each corner a shaped fold, but a novel feature of this invention is the combination with the said fold "and the stringer asses through the said stringer bar and fold only with the head of the rivet in contact with" the exterior surface of the pan-wall. The fold that is made in the sheet-metal blank to form each righta'ngled corner of' the pan, is shown in the drawing; and a hole or opening, 16, is punched or cut through the several thicknesses of this fold; this permits the stem of a rivet, 18, to be inserted with the point-end of the rivet projectingoutwardly or away from the pan-wall, and the flat head of the rivets between the fold, 9, and the panwall, 6, and contacting with the outer surface of the pan-wall. 'The stem of the rivet also extends through a hole in the bar, 17 and the point-end of the rivet at the outer surface of the bar is then expanded or flattened down, in the usual manner of riveting, on the outer surfaceofthe bar. It

willbe seen nopart of the rivet is exposed inside of the pan.

The inventive idea is broad enough to include a fold having'a hole or opening of any shape if the head of the rivet is between theufold and the outer surface of the panwa The form of opening shown in Figs. 2 and 4 is that of a slot, which form is preferred because it compensates for a slight variation in the relative position of the rivet-hole made in the stringer bar, 17.

Having thus described my invention what I claim and desire to secure by Letters Patout is 7 1. A plural number of rectangular shaped individual loaf bread-pans each having at the corners V-shaped exterior folds; a bar extending across two or more of said pans and contacting with said V-shaped folds; and a rivet whose stem extends through the said bar and-V-shaped fold and whose head is between the fold and the outer surface of the pan-wall, whereby there is no exposure of rivet at the inner side of the pan.

2. A plural number of rectangular shaped individual loaf bread-pans each having folds that lay against the exterior wall of the pan a bar extending across two or more of .sai pans and in contact with said folds; and a rivet through said bar and fold with the head of the rivet concealed between the fold and the outer surface of the pan-wall.

3. A plural number of rectan ular shaped individual loaf bread-pans each having at the corners V-shaped exterior folds provided with a slot; 2. bar extending across two or more of said'pans and in contact with said folds; and a rivet through said bar and throu 'h the slot in the fold, the head of the rivet Being in contact with the exterior surface of the pan-wall.

In testimony whereof I aflix my signature in presence of two witnesses.

WILLIAM A. WHALEN.
